Case Sensitivity

In WRspice, case sensitivity of various object names and strings is under program control. Historically the following have all been case sensitive in WRspice:

Function names.
User-defined function names.
Vector names.
.PARAM names.
Codeblock names.
Node and device names.

By default, starting in release 3.2.4, function names and user-defined function names are case-insensitive. Starting in release 3.2.15, parameter names are case-insensitive. The remaining categories remain case-sensitive.

Other SPICE programs may have different case-sensitivity rules, in partiular many of these name categories are case insensitive. To provide better portability of input files, each of the categories above can be set case-insensitive in WRspice.

Case sensitivity must be extablished at program startup and can not be changed during operation. There are two ways to accomplish this:

1. The ``-c'' command line option.
2. The setcase command called in a startup file.

Model names and parameter keywords are case-insensitive, however, unlike other SPICE programs, node names in WRspice are case sensitive by default. One should consider this when importing old SPICE files that use textual node names.
